HDCP Compliance
i
If the HDMI signal is HDCP protected, it can only appear on the
HDMI output if it is connected to an HDCP compliant display.
The VP-461 will not output a picture on an HDMI display that is not
HDCP compliant, nor will a picture be shown on the PC output;
instead it will show a black screen.
In the dual window display mode (see Section 6.2), even if only one
of the inputs is HDCP protected, and is output to a non compliant
display, it will affect the entire screen and turn it black.

Selecting the Correct Aspect Ratio
You can configure the aspect ratio of any output image to fit your application. The
VP-461 offers four different aspect ratio settings: Follow Input, Follow Output, Best
Fit and Letterbox. Here is how each of these settings works.
FOLLOW INPUT – The aspect ratio and resolution of the
input video or graphics signal are both preserved (no
scaling). For example, a composite video image with a 4:3
aspect ratio will appear with the same aspect ratio on a
1080p (16:9) output image, surrounded by black bars
FOLLOW OUTPUT – The aspect ratio and resolution
of the input signal is re-sized to precisely match the
aspect ratio and resolution of the VP-461 output
signal. This may result in some distortion to the input
signal images
BEST FIT – This setting re-sizes the video or
graphics input signal to “best fit” the output resolution
while maintaining the aspect ratio of the input signal.
For example, a composite video signal (4:3 aspect
ratio) will “best fit” to the top and bottom of a
widescreen output image, resulting in black pillars on
either side.
LETTERBOX – This setting compresses the top and
bottom edges of the input signal, but fills the width of
the screen. For example, to preserve a widescreen
film image on a 4:3 display.
VP-461 - The OSD Menu
25
5.7.2
Master Connection Settings
The Master Connection (HDMI or PC) is usually set to the main output display so
that the optimal resolution for that display can be obtained.
By setting the output resolution to Native, the VP-461 is triggered to read the EDID
of the main display and change the output resolution value according to the native
resolution of the display.
If it is not supported by the selected Master Connection, the system searches for
the best supported resolution. If the search fails (for example, if the master
connection is disconnected or EDID is unreadable), the resolution will default to
XGA.

5.8.1
The Luma Keying Feature
The luma keying feature is an easy-to-use method of compositing two video
sources into a single image. By setting up a “key” image or clip on a black
background, it can be merged – or overlaid – onto the primary video. The key
image is transparent in the areas of its dark background, resulting in a picture which
looks as if the key image is cut out and pasted over the primary image. This useful
function of combining images from two different sources is suitable for many
applications, such as sub-titling, labeling, advertising or logo insertion.
To apply the luma keying feature, first set the PiP window to the desired size and
location and then turn luma keying On. The PiP image will show without its
background.
The lower the luminance in the PIP window, the more transparent it becomes, thus
letting the main window image show. The higher the luminance, the less
transparent it becomes, not letting the main window show through. To use this
feature it is recommended to set the PIP image as follows: use low-luminance
colors for the background (the key image portion) and high-luminance colors for the
logo.
i
For certain displays, the screen may flicker once for about a second
after activating or changing the luma keying setting.
Since luma keying is a volatile parameter, it may reset unexpectedly
following a change in the setup. So we recommend that you
activate it after completing the setup.
When the luma keying feature is On, any change in the setup
(either by the user or by resetting due to a setup change) may
cause the screen to flicker once. The luma keying will recover
automatically after resetting.

VP-461 - Technical Specifications

The VP-461 RS-232 Communication Protocol
The Kramer Protocol lets you control the VP-461 from any standard terminal
software (for example, the Windows® HyperTerminal Application).
10.1
Using the Communication Protocol
There are three different methods to control the VP-461 via RS-232:

Protocol commands (via protocol 3000) mimicking the OSD, see Section
10.2

The button functions mimicking the remote controller buttons (as well as the
front panel buttons), see Section 10.3

Protocol 3000 common commands, see Section 10.4
i
All three tables together include all the protocol commands, but they
are not identical and do not always include the same information.
Some of the data may appear in one or two of the tables but not in the
third table and vice versa.
The protocol 3000 communications protocol uses a data rate of 115200 baud, with
no parity, 8 data bits, and 1 stop bit.
10.2
Communication Protocol: Mimicking OSD
The audio/video protocol commands defines all the function numbers, their valid
parameters can be used with protocol 3000.
10.2.1
Using the Communication Protocol with Protocol 3000 (the “Y”
Command)
Set Command:
Type in: “Y Control_Type=0,Function,Param”
Reply: “~id=01Y Control_Type=0,Function,Param OK”
Set command example, set window control (721) to PiP:
Send: “#y 0,721,1”
Reply: “~01@Y 0,721,1 OK”
42
VP-461 - The VP-461 RS-232 Communication Protocol
Get Command:
Type in: “Y Control_Type=1,Function”
Result: “~id=01Y Control_Type=1,Function,Param”
Get command example: get window control setup (721):
Send: “#y 1,721”
Result: “~01@y 1,721,1”
i
You can add a last parameter, to be located fourth in SET or third
in GET, to define a specific window.
For example:
Set H Sharpness value to 10 on the PiP window (1): “#y 0,510,10,1”
Get H sharpness of the Main window (0): “#y 1,510,0”
The “Y” command also supports the value increment/decrement of any command
using the ‘+’ or ‘-‘ signs as the third parameter of the “Y” command.
For example, move the PiP window one step to the left
Send: “#Y 0,141,-,1<CR>”
Reply: “~01@Y 0,141,-,1 OK”
For example, in order to increase zoom on the main windows type “#Y
0,650,+,0<CR>”.
Send: “#Y 0,650,+,0<CR>”
Reply: “~01@Y 0,650,+,0 OK”
10.2.2
Protocol Table: Mimicking OSD
You can associate a function number to its description and valid parameters
intuitively by navigating the OSD menu according to the following logic: A function
number is directly related to its location in the OSD menu.
For example, the third menu on the OSD is Process (3 in the hundreds). The
second menu item in Process is Film Mode (2 in the tens), therefore the function
number for it will be 320 (3rd item on the Main Window Control and the 2nd item in
the Process submenu (see also Section 5.1). When navigating in the OSD MENU
you will be able to see the Film Mode valid parameters.
The following table defines the protocol commands:
